WM. H. ELLIOT, OF PLATTSBURG, NEW' YORK.

PRINTING-STAMP.

Specification of Letters Patent No. 16,641, dated February 17, 1857.

To @ZZ whom t may concern Be it known that I, VM. H. ELLroT, or' Plattsburg, county of Clinton, State of New York, have invented a new and improved Printing Stamp; and l do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Similar letters of reference indicate the same parts in each drawing.

The nature of my inventionconsists in the employment of certain devices by which the die is carried from the impression pad to the inking apparatus, and back again to the Vimpression pad so that the die or type is inked and the impression made by the application of force by the hand or foot, the power being applied in one direction only; the motion of the die being controlled by cranks or arms in connection with a spring' or weight.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

Figure 1, kelevation of the printing stamp. Fig. 2, plan of crank F with pulleys. Fig. 3, plan of crank H. Fig. 4, elevation of crank H, and spring P, combined in one piece, with a portion of the frame and die carrier.

A, frame; B, die or type carrier, C, die; D, inking apparatus; E, impression pad; F, crank being attached to the trame at Q and turning upon that point being attached also to the die carrier at S; G, pulley attached to crank F and turning` with it on pins Q; I, another pulley attached like. pulley G; K, weight; L, cord attached to pulley Gr, at one end passing over pulley Gr and attached at the other end to weight K; L, cord attached to pulley I passing over I and attached at the other end of treadle M; N, hinge ot treadle; O, spring for tilting` the inking apparatus; P, spring; combined spring and arm, or crank; o, dotted lines showing another method of carrying the die to the inking apparatus; lV, position of inking apparatus when the die carrier occupies the position represented by b; X, position ofthe die carrier when the die is receiving the ink.

Operation: The die carrier is represented in Fig. l in the position of giving the impression, being driven down by the hand. As the hand is removed the spring P in its tendency to straighten presses against projection g/ on arm or crank H and causes said crank to rise suddenly. Then the middle of the spring comes in contact with stop e, it ceases to act upon crank H, but the impetus which the several parts have acquired from the power of the spring, causes crank H to rise sufficiently high to allow the crank F to pass over from right to left, placing the die over the inking apparatus, the die carrier occupying the position indicated by dotted lines a', on nearly that position. Then the die carrier is driven down in this position the crank H assumes the position indicated in the drawing. and as the hand is removed the parts again rise by the force of the spring and are carried and remain suspended over the impression pad, ready to be driven down for the purpose of making the impression, so that by the combined action of the spring P, and arm or crank H, the die is caused to bound alternately from the impression pad to the inking apparatus and back again to the impression pad, being put in motion simply by the force of the hand upon the top of the die carrier. In its operation by the foot the cord L being attached to the weight K at one end and to pulley Gr at the other end, and the pulley G, being attached to crank F, the tendency of the weight is to cause the crank F to revolve from right to left carrying the die from the impression pad and placing it upon the inking apparatus, and then by depressing the treadle by the foot, the cord L being attached to the lower side ot pulley T at one end and to the treadle at the other end causes the crank F to revolve from left to right carrying with it the die and placing it upon the impression pad with sufficient force to produce the impression, so that by each depression of the treadle an impression is obtained.

Pulleys G and I only serve for the cords to pass over so as to give them the desired direction. Another method is shown by dotted lines Z) of carrying the die from the impression pad to the inking apparatus, and back again; which varies from the first only by making the crank H, the saine length of the crank F, and pivoting it, as represented, to the frame at R. In this case the two cranks revolve alike. -W, shows the position that the inking apparatus would occupy in case crank H were made as represented at b.
